Confirming, with a note: the errors in bug-seams are not full_row,
but the upper half of row 74 is rendered by sub_row whereas the lower
part is rendered by full_row. The two are not complementary.
Skimming the new code I'm not sure whether (lines 795...) it is correct
to use edge->cell there, to me it seems that edge->cell is the x at the
y of first subrow's center and for edges nearly horizontal it could be
slightly off with respect to the x corresponding to the y at the start
of the row. (it could be compensated in the code later though)</pre>
